Condensation/boiling point is -182.95 degrees Celsius
The solid and liquid forms of Oxygen are pale blue.
Oxygen is odorless, tasteless, and colorless as a gas.
An oxygen molecule is made up of two atoms of oxygen.
History
Oxygen was first discovered as an individual gas by Joseph Priestely and Carl Wilhelm Scheele. Although Scheele discovered it two years before Priestely, Priestely separately discovered oxygen and published his results the same year as Scheele.
Oxygen was first discovered as an individual element in Europe, in 1772.
Oxygen can be found throughout the Sun, the Earth's atmosphere, the Earth's crust, and the human body.
General Information
All known forms of life rely on oxygen to breath.
Oxygen is an extremely reactive element. It will quickly combust with fire.
Oxygen is only found as a gas at earth temperatures.
Oxygen is the third most common element in the universe after hydrogen and helium.
Oxygen has three naturally occuring isotopes: Oxygen-16(99.765%),Oxygen-17(0.1995%), and Oxygen-18(0.0355%). None of the three are radioactive.
Modern day uses for oxygen include it being prescribed by hospitals for patients with breathing problems, and for respiration by animals and plants.
The retail value of oxygen is 5 cents per cubic foot for small amounts and 15 dollars a ton for large amounts.
